Answer:
systematic sampling
Step-by-step explanation:
This is when you start at a person (using a number that is randomly generated) and go up in intervals to select a sample.

ANSWER
D. 224
EXPLANATION
The given series is
The first term of this series is
The last term of this series is:
The sum of the first n-terms of the series is calculated using the formula,
Dilation refers to a non rigid motion where a figure is transform and its image has the same form but a different size measure.Dilation is define by the rule (x,y)-- (kx, ky) where k represents the scale factor.
On this exercise is given that a triangle with vertices A(-6,-3), B(7,-7), and C(0,3) was dilated by a scale factor of 1.5, and it is asked to find the vertices of the image of the triangle after the dilation occurred.
Pre-image Image
A(-6,-3) --- (-6*1.5,-3*1.5) --- A'(-9,-4.5)
B(7,-7) ---- (7*1.5,-7*1.5) ---- B'(10.5,-10.5)
C(0,3) ----- (0*1.5,3*1.5) ----- C'(0,4.5)
The coordinates of the triangle's image after a dilation with a scale factor of 1.5 are represented by the points A'(-9,-4.5), B'(10.5,-10.5), and C'(0,4.5).
